Angmar receives new siege mechanics in Edain 4.5. From the forge, you can recruit troll siege crews. They can build your siege weapons directly on the battlefield. This allows for the same flexibility as the trallmasters. Additionally, this new system makes siege towers possible for Angmar. They couldn't be built inside the fortress because then they'd be too large to get out of the gate. However, the trolls can construct them in the open field without problems.

Gondor has now besides the catapults and rams another siege weapon: The Siege Shield.

The Siege Shield is an economical siege unit which provides passive immunity against arrow and spear damage.This makes it possible to get close to the enemy fortress, without being stopped by arrow fire.

In the next Edain patch 4.5 the defense buildplots have been improved. Every faction has now the possibility besides the battletower to build a second special building on these plots.Rohan, Gondor, Rivendell and the Dwarves can build a heroic statue (camp maps). Mordor can build a Banner, which improves the recruitment speed of recruiting buildings in the near. Isengart has the possibility to build a warg sentry, which isn't any longer available at the big buildplots. And Angmar can build some Obelisk, which reduces the armor and damage of nearby enemy troops.With these changes we hope to incorporate a little more diversity in the siege system.

The Mineworkers can dig a tunnel entrance in the near of an enemy building, in which they undermine targeted enemy buildings and walls. The radius to an enemy building is indicated by a radial selection graphic and a light at the helm of the dwarf.If the tunnel gets destroyed or even torn, the Mineworker leaving the underground caves and can be used again, but only after the ability has been recharged.

After some critism by our fans, we decided to rework some of the shown new defense buildings.Angmar doesn't build anymore the Obelisks, now there are the Cages available, which are already known as a wall upgrade.Mordor's Defense Banner has been changed too: Now it does fit more the common style of Mordor's buildings.Isengard's Warg Sentry got some rework, we changed the bone thing. Now it should fit more the wooden style of Isengard.

Petardiere are siege units which throwing burning pitch bags on enemy buildings and cause high damage.Hay Cart can be dropped off at enemy buildings and gates and ignited. The inflammation works automatically by the auto attack of the cart.After a while the inflamed Hay Cart burns down and disappears. The enemy, however, can counter the burning Cart by destroying it.
